Does anyone know whether its possible to control the size of the pl/sql static cursor cache.

I'm running into ORA-01000: maximum number of open cursors exceeded errors and part of the problem (apart from the usual developers not closing explicit cursors) is that _all_ static sql statements in compiled pl/sql units seem to be getting cached. I can't find any documentation of this feature apart from a few hints in the pl/sql and application development docs. Here's an example from an 8.1.7 database: -

SQL>create or replace procedure foobar is   2 v_result varchar2(30);
  3 begin
  4 select user into v_result from dual;   5 end;
  6 /

Procedure created.

SQL>
SQL>select b.sql_text
  2 from v$session a, v$open_cursor b
  3 where a.sid = b.sid
  4 and a.audsid = userenv('SESSIONID')   5 /

SQL_TEXT

SELECT SYS_CONTEXT(:b1,:b2) FROM SYS.DUAL select b.sql_text from v$session a, v$open_cursor b where a.

SQL>
SQL>exec foobar

PL/SQL procedure successfully completed.

SQL>
SQL>select b.sql_text
  2 from v$session a, v$open_cursor b
  3 where a.sid = b.sid
  4 and a.audsid = userenv('SESSIONID')   5 /

SQL_TEXT

SELECT SYS_CONTEXT(:b1,:b2) FROM SYS.DUAL select b.sql_text from v$session a, v$open_cursor b where a. SELECT USER FROM DUAL TIA
